Why is there no sound when my Bluetooth headset is connected?

If you use vivo phones and Bluetooth headsets, you can refer to the following methods for troubleshooting:

1, deeply adapted model, connected with Bluetooth headset. When entering or exiting the game, the Bluetooth codec will automatically switch to the low delay of the game, and the sound will be temporarily interrupted, which makes people feel stuck.

2. Headphones may be disconnected due to power failure or interference from environmental signals. Please put it in the charging box to check the power of the earphone and reconnect it.

3. If you still can't use it again, please press and hold the function key 15 seconds to reset the earphone and try to connect again. If the problem is still unresolved, please go to the vivo customer service center, enter the vivo official website-My service outlet, select a province or city to inquire the address and contact information of the local service center, or click the webpage link to search for the address of the service center.
